Oxygen effects on uranium tested
A team of researchers from Lawrence Livermore National Laboratory (LLNL) and the University of Michigan has found that the rate of cooling in reactions dramatically affects the type of uranium molecules that form. The team’s experimental work, conducted over about a year-and-a-half starting in October 2020, attempts to help understand what uranium compounds might form in…
Physics-based cryptocurrency transmits energy (not just information) through blockchain
Researchers from Lawrence Livermore National Laboratory (LLNL) have devised a physics-based cryptocurrency that links electrical energy and blockchain technologies in a new way. This new blockchain concept, dubbed “E-Stablecoin,” could allow electricity to be transmitted between users who are spread around the world, without the need for interconnecting wires or a grid…
DOE honors three early-career Lab scientists
Three scientists from Lawrence Livermore National Laboratory (LLNL) are recipients of the Department of Energy’s (DOE) Office of Science Early Career Research Program award. Mimi Yung, John Despotopulos and Timofey Frolov are among 83 awardees receiving the recognition. Under the program, typical awards for DOE national laboratory staff are $500,000 per year for five years…
Additive Manufacturing Brings New Possibilities for Transparent Ceramics
Having developed several transparent ceramics for radiation detection applications for the Department of Homeland Security and the Stockpile Stewardship Program, Lawrence Livermore recently leveraged its unique additive manufacturing resources and capabilities to develop transparent ceramics with properties not previously available for use as laser materials.
Three Lab postdocs selected to attend the 71st annual Lindau Nobel Laureate meeting
Three Lawrence Livermore National Laboratory (LLNL) postdoctoral appointees have been selected to attend the 71st annual Lindau Nobel Laureate meeting in Germany this summer thanks to the University of California President’s 2022 Lindau Nobel Laureate Meetings Fellows Program. The three selected to attend are Magi Mettry, Johanna Schwartz and Dane Sterbentz. The Lindau…
Science on Saturday lectures break down the CO<sub>2</sub> problem
Throughout the month of February, scientists from the Physical and Life Sciences (PLS) directorate virtually participated in three of the four 2022 Science on Saturday (SOS) lectures, presenting on the theme “Energy and the Environment.” The SOS lecture series is an annual collaboration between scientists at Lawrence Livermore National Laboratory (LLNL) and staff members…
Paving the way to tailor-made carbon nanomaterials and more accurate energetic materials modeling
Carbon exhibits a remarkable tendency to form nanomaterials with unusual physical and chemical properties, arising from its ability to engage in different bonding states. Many of these “next-generation” nanomaterials, which include nanodiamonds, nanographite, amorphous nanocarbon and nano-onions, are currently being studied for possible applications spanning quantum…
Lawrence Livermore shares recommendations for Microsoft to reach carbon-negative goal
Lawrence Livermore National Laboratory (LLNL) scientists have provided input on Microsoft’s pathway to become carbon-negative by 2030. LLNL researchers built on their pivotal report "Getting to Neutral: Options for Negative Carbon Emissions in California," which has become a trusted adviser in the discussion of how to remove carbon dioxide from the air, to make…
Putting the pedal to the metal crossing the solid-liquid interface
Most metal alloys are prone to corrosion, which costs hundreds of billions of dollars of damage annually in the U.S. alone. Accurately predicting corrosion rates is a long-standing goal of corrosion science, but these rates depend strongly on the specific operating environment. At the atomic scale, these environmental factors are associated with how quickly and easily…
Researchers take closer look at stimulated Brillouin scattering
A major cost of running the National Ignition Facility (NIF) is managing and mitigating laser-induced damage to optics as the laser beams propagate to the target. Another damage mechanism stems from stimulated Brillouin scattering (SBS) as light travels back from the target and with nearly the same wavelength as the incoming light. This SBS has the potential to cause…
Two LLNL scientists chosen for 2022 DOE Project Leadership Institute
The Department of Energy (DOE) Project Leadership Institute (PLI) has selected Lawrence Livermore National Laboratory’s Lara Leininger and Al Churby as 2022 cohort participants. Members of the PLI cohort have demonstrated their expertise as technical, business systems or project leaders, with significant experience and responsibility for project or organization performance…
Taking a look at tiny bubbles
The formation and collapse of microscopic bubbles is important in a wide range of fields as both a potential mechanism behind tissue damage, such as in cases of blast-wave-induced traumatic brain injury, and as a useful tool for technology applications, such as mechanical properties evaluation, nanomaterials manipulation and surface cleaning. Nanobubbles have been of…
Capturing microbes in soil and plants
Lawrence Livermore National Laboratory (LLNL) scientists have developed a custom microscope to image microbes in soil and plants at the micrometer scale. Live imaging of microbes in soil would help scientists understand how soil microbial processes occur on the scale of micrometers, where microbial cells interact with minerals, organic matter, plant roots and other…
Two LLNL scientists honored as 2022 Oppenheimer Science and Energy Leadership fellows
The Oppenheimer Science and Energy Leadership Program (OSELP) has selected Lawrence Livermore National Laboratory computer scientist Kathryn Mohror and materials scientist T. Yong Han as 2022 fellows. Established in 2017, OSELP is a distinguished fellowship program that brings together exceptional leaders to explore the complexities, challenges and opportunities facing the…
Breaking down the barriers in all solid-state batteries
Solid electrolytes may overcome key technological hurdles associated with the narrow electrochemical and thermal stability of conventional lithium (Li)-ion and sodium (Na)-ion batteries. However, many solid electrolytes — ceramics in particular — also suffer from poor cycling issues and limitations in their ability to efficiently transport ions. These limitations often…
Multiscale simulations of metal additive manufacturing processes
Much of the latent promise of metal additive manufacturing (AM) rests in the potential for controlled creation of spatially tailored microstructures, designed to optimize key build-scale properties through systematic variation across a build. Component optimization possibilities and performance potential expand enormously when this becomes possible. However, the extreme…
Pandora mission to study stars and exoplanets continues toward flight
The Pandora mission, co-led by a national laboratory and a NASA flight center, has passed a crucial step on its path to study stars and planets outside our solar system, or exoplanets. After a successful concept study report and system requirements review, NASA approved the mission to continue toward flight. Lawrence Livermore National Laboratory (LLNL) and NASA’s Goddard…
Unprecedented multiscale model of protein behavior linked to cancer-causing mutations
Lawrence Livermore National Laboratory (LLNL) researchers and a multi-institutional team of scientists have developed a highly detailed, machine learning-backed multiscale model revealing the importance of lipids to the signaling dynamics of RAS, a family of proteins whose mutations are linked to numerous cancers. Published by the Proceedings of the National Academy of…
